The political action committee of the Congressional Black Caucus has endorsed Hillary Clinton.

Rep. Gregory Meeks said Thursday that the Democratic presidential candidate has been a long term partner who understands the racial divide.

In a tacit swipe at Sen. Bernie Sanders, Meeks said her knowledge of the racial split wasn't something Clinton acquired recently.

Members of the CBC board including civil rights icon John Lewis said they would travel to South Carolina to campaign for Clinton.

The announcement, anticipated days, came at a news conference at Democratic Party headquarters in Washington.

The political action committee is separate from the Congressional Black Caucus, not all of whom have endorsed Clinton. Reps. James Clyburn of South Carolina and Barbara Lee of California have not endorsed a candidate. And Rep. Keith Ellison, D-Minn., has endorsed Sanders.

John Kasich says he's a "scrappy guy" who won't "take crap from anybody" — but he's still pledging to run a positive campaign.

Speaking to voters at a pancake house on South Carolina's coast Thursday, the Ohio governor is responding to questions over how he'll cut through the noise of a chaotic GOP race.

Kasich notes his rivals are already ramping up attacks against him after his second place finish in New Hampshire on Tuesday. He says he'll defend his record, but doesn't see the point of running a negative campaign. Still, he's giving Jeb Bush a poke.

Marco Rubio is turning up the heat on his Republican rivals as he campaigns in South Carolina.

The Florida senator jabbed Donald Trump, Ted Cruz and Jeb Bush on national security while facing hundreds of South Carolina voters at an Okatie retirement community Thursday morning.

"Donald Trump has zero foreign policy experience — negotiating a hotel deal in another country is not foreign policy experience," Rubio charged.

He also questioned Bush's foreign policy experience and criticized Cruz for supporting military budget cuts.

Rubio's sharp remarks come a day after he promised to be more aggressive with other Republicans after faltering in last week's debate — a performance he has apologized for after his fifth place finish in the New Hampshire primary.
